Traditionnally dedicated to ancient perfumery and cosmetology in France, SAS LJB funded a R&D program since 18 months to develop breakthrough IOT smart devices to get multisensorial communication using 5D screens including olfaction. This olfaction synchronized with video will trigger emotion from the consumer but also a better memorization. Coupled with processors and cameras, the devices called SNIFFY (Sniffy Market, Home, Theatre, Home, Street) will be implemented in any place offering digital screens to promote products or services (Retail, Food and Beverage, Beauty, entertainment...). The camera will collect unique consumer behaviour triggered by olfaction to analyze the sales pattern in order to help any industrial to understand how te sell better and more. SNIFFY, who KNOWS ?
